Abstract
A method is described for rendering total liquid product hydroisomerates daylight stable and improving their oxidation stability, which method involves treating the hydroisomerate total liquid product with a Group VIII metal on refractory metal oxide catalyst or Group VIII metal on halogenated refractory metal oxide catalyst under mild conditions, which conditions are a temperature in the range of 170.degree. to 270.degree. C., a pressure in the range of 300 to 1500 psi H.sub.2, 0.25 to 10 v/v/hr and 500 to 10,000 SCF/B,H.sub.2.
